Overview:

The DSS Racing 5.7 Stroker Small Block Mopar Hemi Gen III FX Series Forged Piston Set is engineered for enthusiasts and builders seeking enhanced durability and performance in their 5.7L Hemi engines. Designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi models, these pistons are ideal for stroker builds and high-performance applications. With a forged construction and precise specifications, this piston set delivers reliable strength and improved combustion efficiency for street, strip, or off-road use.

Whether upgrading an existing engine or building a stroker from the ground up, these pistons provide the foundation for increased power and longevity under demanding conditions.

Key Features:

This piston set incorporates advanced design elements and high-quality materials to meet the rigorous demands of performance engines:

• Forged construction for superior strength and durability
• Comp height of 1.21 inches optimized for Gen III 5.7L Hemi stroker builds
• +9cc dome top design to enhance compression and combustion efficiency
• Pin diameter of .927 inches compatible with full-floating or press-fit configurations
• Ring groove dimensions of 1.2mm / 1.2mm / 3mm for reliable ring sealing and reduced blow-by
• Stroke length of 3.795 inches matched to a 6.125-inch connecting rod for precise fitment
• Available in multiple dome volumes (65cc, 74cc, 85cc) to achieve compression ratios ranging from 10.03:1 to 12.86:1
• Designed specifically for the Small Block Mopar Hemi Gen III FX series engines

Construction & Design:

DSS Racing pistons are crafted from high-grade forged aluminum alloy, providing an excellent balance of lightweight properties and structural integrity. The forging process enhances grain structure and strength, allowing these pistons to withstand the high pressures and temperatures typical of performance and stroker engines.

The dome top design with varying volumes allows builders to tailor compression ratios to their specific needs, whether for naturally aspirated or forced induction setups. Precision machining ensures tight tolerances for optimal ring seal and piston-to-wall clearance, reducing friction and wear over time.

Installation & Fitment:

This piston set is designed to fit most Chrysler, Dodge, Jeep, and Ram 5.7L Hemi engines equipped with the Gen III FX series small block configuration. Installation requires standard engine assembly procedures and may involve balancing and blueprinting for stroker builds. The pistons accommodate either full-floating or press-fit wrist pins, providing flexibility depending on the engine builder’s preference.

Proper ring installation and torque specifications should be followed to ensure long-term reliability and performance.

What's Included:

• Set of forged pistons (quantity as required for engine configuration)
• Wrist pin compatibility for full-floating or press-fit applications
• Precision-machined ring grooves for 1.2mm top and second rings, 3mm oil ring

Ideal For:

This piston set is ideal for automotive enthusiasts, engine builders, and racers looking to upgrade or build a robust 5.7L Hemi stroker engine. It suits applications ranging from street performance to competitive drag racing and off-road use where increased durability and compression tuning are essential.
